Optimized
VPN Solution for Satellite Networks |
| The inherent architecture
of satellite networks causes significant
and unavoidable end-to-end propagation
delays ranging between 350 and 500 msecs
that negatively impact overall network
performance. These delays present a
technical challenge to Satellite Network
Operators (SNOs) who want to leverage
existing networks and capital investments
while at the same time offering their
global enterprise customers additional
high-margin, value-added services, such
as high speed Internet access and Virtual
Private Network (VPN) capability. More... |

Performance VPN Solutions Over
Satellite Networks |
Satellite Networks
have inherit round-trip delay
characteristics of about ½ second for typical
geo-stationary satellite
circuits. Such delay, which pauses
some performance issues for voice applications,
might lead to problems such as
“conversation collisions” where
both parties can be talking at
the same time. More... |

| Issues and Solutions for IPsec VPNs Over Satellite Networks |
| Satellite networks have always posed a problem to network designers; the limited bandwidth available on the satellite and the high-latency of the round trip of a signal between the satellite hub, the satellite and the satellite service subscriber impose restrictions on what types of information can be transmitted.

| Preserving
End-to-End Quality of Service
For IP VPNs Over MPLS Satellite
Networks |
| Enterprise users
increasingly look to MPLS providers
for services to replace traditional
leased lines and as less ex-pensive
alternatives to virtual circuit
services, mostly Frame Relay
and ATM. Federal Agencies in particular
look to outsourced MPLS as a way to
respond to requirements that government
operations, including private networks,
be opened to competition from private
firms. More... |
